When in break mode within Visual Studio, you can view the call stack in the Call Stack window.

When you bring up the Call Stack window, there will be a yellow arrow pointing to the top of the call stack, indicating the location of the next statement that will execute when you resume execution. The Locals window will show the values of local variables within the current method.

At this point, you can double-click on another method within the call stack. When you do, the code editor will show code for that other method and the Locals window will show local variables for the same method. They will have the values that existed at the point that the method at the top of the call stack was called. Notice that a yellow arrow still indicates the execution point, but a green arrow now appears, showing the current method being examined.
